p Claims. (Cl. 242-544) This invention concerns a device for supportingand moving the ball roll of a balling head of single or double pin-fieldgill boxes for combing and drawing of natural and artificial fibers.

It is an object of the present invention to provide a baller in whichthe ball roller or winding spool is maintained inconstant engagementwith the driving roller or rollers.

It is another object of the present invention to provide a baller inwhich the'mechanism by means of which the ball roller is maintained inconstant engagement with the driving roller or rollers is of very simpleand rugged construction.

The objects of the present invention also include the provision of aballer capable of accomplishing the above objects, which baller isfurther adapted to be so manipulated as to make the removal of a woundball very easy.

With the above objects in view, the present invention mainly resides inthat improvement in a baller which comprises a ball roller adapted tohave a sliver wound thereon, mounting means for mounting the ball rollerfor rotation about a first axis and for movement along a path lying in aplane containing this first axis, a driving roller mounted for rotationabout a second axis parallel to the first axis, the driving roller beingso positioned as to be adapted to be engaged by the sliver wound uponthe ball roller, and yielding biasing means connected to the mountingmeans for continuously urging the ball roller for movement along thepath toward the driving roller so that the same continuously engages thesliver wound upon the ball roller.

The present invention is described with reference to the enclosed sketchand both the description and the sketch are not restrictive but aremerely given as an example.

The only figure of the sketch is the side elevation of the preferredembodiment of the device.

Referring now to the drawing, A shows the frame of the machinesupporting the sloping rod .1 which slides axially. The sloping rod hasat its end the horizontal arbor 2 carrying the ball roll 3. Rod 1, whichcannot rotate because of the longitudinal key 4, has at the bottom arack 5 meshing with a toothed wheel 6 supported by the frame A of themachine. A chain or sprocket wheel 7, supporting the chain '8 is keyedon the axle of the wheel 6. One of the ends of the chain carries theweight 9, and the other end is fastened near the loose This pedal ispivotally mounted on the frame A by a suitable joint 1-2.

In the position shown in the sketch the weight 9 tends to rotate thewheels 7 and 6 in the direction of arrow X, and this, in turn, tends tomove axially rod 1 in the direction of the arrow Y. Ball roll 3 istherefore pressed against winding or driving rolls 13 and the sliver 14is normally wound on the ball roll 3. As the diameter of the ballincreases, rod 1 is automatically moved in the opposite direction ofarrow Y, this movement being counteracted .by the weight 9'.'

At the end of the winding operation, or in the event posite'to the oneshown by the arrow X, and this, in

turn, will cause the rod 1 to move upwardly in the di-. rection oppositeto the one shown by the arrow Y. Thus, when the arbor 2 is in the raisedposition, the ball. roll 3 may be removed, or, in the event of breakageof the sliver, the same may readily be knotted.

- A suitable detent arrangement is provided for maintaining the pedal,whenever desired, in depressed condition. In this way, the ball roll maybe held in the up position without it being necessary for the operatorcontinuously to hold the pedal down. Such detent arrangement includes abell crank lever having a downwardly extending arm 15 and a generallyhorizontallyextending .ar'm-18 which extends in the direction of thepedal I l. The lower end of the arm 15 is formed with a nose 16adapt'ed'to engage a cross piece 17, the arrangement of thelparts beingsuch that when the pedal 11 is depressed, the lower end of the arm 15will first cam past the cross piece 17 and upon, release of the pedalwill engage this cross piece, thereby preventing upward movement of thepedal. Release of the detent means is effected by depressing the arm.18.

It is understood, of course, that the details of the device may varywithout losing the present industrial protection.

In the claims:

1. In a ballet, in combination, a ball roller adapted to have a sliverwound thereon; mounting means for mounting said ball roller for rotationabout a first axis and for movement along a path lying in a planecontaining said first axis, said mounting means including a movableelement movabe in the direction of said path; a driving roller mountedfor rotation about a second axis parallel to saidfirst axis, saiddriving roller being arranged in said path and adapted to be engaged bythe sliver wound upon said ball roller; yielding biasing means connectedto said movable element of said mounting means for continuously urgingsaid ball roller for movement along said path toward said driving rollerso that the same continuously engages the sliver wound upon said ballroller; and control means operatively connected to said movable elementof said mounting means for moving, whenever desired, said movableelement and said ball roller along said path away from said drivingroller against the action of said biasing means.

2. In a baller, in combination, a ball roller adapted to have a sliverwound thereon; mounting means for mounting said ball roller for rotationabout a first axis and for movement along a path lying in a planecontaining said first axis, said mounting means including a movableelement movable in the direction of said path; a driving roller mountedfor rotation about a second axis parallel to said first axis, saiddriving roller being arranged in said path and adapted to be engaged bythe sliver wound upon said ball roller; yielding weight means connectedto said movable element of said mounting means for continuously urgingsaid ball roller for movement along said path toward said driving rollerso that the same continuously engages the sliver wound upon said ballroller; and control means operatively connected to said movable elementof said mounting means A taining said first axis, said mounting meansincluding an elongated mounting element extending in the direction ofsaid path; a driving roller mounted for rotation about a second axisparallel to said first axis, said driving roller being arranged in saidpath and adapted to be engaged by'the sliver Wound upon said ballroller; yielding weight means connected to said mounting means forcontinuously urging said ball roller for movement along said path towardsaid driving roller so that the same con-l tinuously engages the sliverwound upon said ball roller, said weight means including a toothed rackon said mounting element and extending in the direction of its, length,a gear mounted for rotation about a third axis and meshing with saidtoothed rack, a pulley also mounted for rotation about said third axisand rotatable with said gear, a cable power-transmittingly engaging saidpulley, and a weight connected to said cable at one end thereof, saidcable and weight being so arranged as to cause said pulley andconsequently said gear to rotate about said third axis in such a senseas will cause said gear to move said rack and consequently said mountingelement in that direction as will bring about movement of said ballroller along said path toward said driving roller; and moving means formoving, whenever desired, said ball roller along said path away fromsaid driving roller against the action of said weight means, said movingmeans including control means connected to the opposite end of saidcable for moving the same in a direction opposite to the direction inwhich said weight tends to move said cable, whereby a force may beapplied to said cable in opposition to the force exerted by said weight,thereby causing said pulley together with said gear to rotate about saidthird axis in the opposite sense thus causing said gear to move saidrack and consequently said mounting element in that direction as willbring about movement of said ball roller along said path away from saiddriving roller.

4. The combination defined in'claim 3 wherein said control means includea foot pedal and foot pedal mounting means for mounting said foot pedalin such a manner that said cable is moved in opposition to the forceexerted by said weight'when said foot pedal is depressed.

5. The combination defined in claim 4, and detent meansoperativelvassociated with said foot pedal for maintaining the same,whenever desired, in depressed condition, whereby said ball roller may,without foot depression of said foot pedal, be maintained insuch aposition wherein the sliver wound upon said ball rolleli is out ofengagement with said driving roller.
